Essentially, the picking finger of the present invention consists of a stretchable and; elastic finger, which has a weak portion intermediateits ends and a heavier-portion at its outer end. By reasonof this novel construction, the outer; end of the-finger, when the'finger is rotated on a drum, flies out by centrifugal force and strikes w he r s the fowl.

Referring now in detail to-the drawings, Fig-1. ures 1 and 2 show a poultry-picking machine in which the novel picking finger of the present invention may be. employed. The machine. is indicated as a whole by the reference numeral; l2 and inoludesashellor tunnel M, open' .at both endsr: A conveyor-is. indicated at' I-G and extends through themachin'e 12. :A number; of fowl I8 are suspended from the conveyor. 16a and are carried through the machine 2 forexample, from left to right in Figure 1.
tween adjacent surfaces of adjacent-ribs.
Picking drums are indicated at 2B and are illustrated only diagrammatically. Each picking drum includes a central cylinder 22 having a shaft 24 for mounting the drum in the machine l2. Preferably, the drums 2|] are disposed in an inclined position with their upper ends toward the entrance of the machine.
Each picking drum 26 includes a plurality of picking fingers 26 which extend radially outward 1y from the cylinder 22. The fingers 26 are arranged in longitudinal rows on the drum and there are a number of such rows spaced circumferentially around the drum so that in. the
final completed drum there are a large number of fingers. The drums 20 are rotated in opposite directions 50 that as the fowl pass between the drum the fingers engage the fowl from all sides.
Figure 3 illustrates a finger 26 which forms one embodiment of the present invention and a number of which are employed as described in connection with Figure 2. Afragment of the cylinder 22 is illustrated. Although the cylinder 22 is generally cylindrical, it is provided with a fiat portion 28 for securement of the fingers 22 thereon. The finger is formed of stretchable elastic material, such as rubber. The finger, at its inner end, has an enlarged portion 36 forwardly of which is a circumferential groove 32. v The portion 28 of the cylinder 22 is provided with a hole 34, in which the finger is securedto the cylinder. Outwardly of the groove 32 is a tapered portion 36 of which the greatest diameter is larger than the groove 32, but smaller than the enlarged portion 30. Outwardly of the tapered portion '36 is an intermediate shank portion 38 which is of lesser transverse dimension than any part of theinner end of the finger and has less mass per unit length thereof. Outwardly of the central reduced, or weak; portion 38 is another tapered portion 40 which enlarges outwardly, terminating in an outer end portion 42. The outer end portion 42 is generally uniform longitudinally, but is provided with a plurality of circumferential ribs 44 spaced axially thereon. The ribs 44 extend radially outwardly a distance a beyond the periphery 43 of the finger an'ext'ent at least as great as the distance b be- The ribs 44 are adapted to flex over and engage the adjacent rib on either side "as indicated at 46. Formed in the outer end of the outer portion42 is a cavity 48 for reducin the mass of the outer end of the finger. The finger 26 is inserted inthe opening 34 by stretching the finger to reduce its diameter, whereby the outer end and the tapered portion 36 can be inserted therethrough. I
50 includes an intermediate portion 58 which is 5 preferably cylindrical and elongated. The intermediate portion 58 is of less diameterand of less mass per unit length than the central por- Outwardly of the intermediate portion 58 is an outer portion 60 which is preferably solid in construction. A plurality of circumferential Upon release of the stretchin force, the-margin of the opening 34 fits inthe groove 32.
Figure 5 illustrates another embodiment of th present invention and comprises a double finger or opposite-extending single fingers, secured to a common base portion. A cylinder 50 is employed for .mounting the double finger. The cylinder 50 is of considerably less diameter than the cylinder 22 used in connection with the previous finger; the purpose of the smaller dimension cylinder 50 will be described later. r i
The double finger illustrated in Figure 5 is also made of'resilient material which is stretchable and elastic. The double finger includes a'central portion 52 which is generally cylindrical and is" preferably uniform throughout its len'gth. At each end of the central portion 52 is an enlarged circumferential abutment 54 considerably larger in diameterthan the central portion 52. The central portion 52 and the abutment's 54, to-- ribs 62 are provided on the outer end portion 60 and are spaced axially therealong. As in the case of the previous embodiment, the ribs 62 extend radially outwardly from the periphery of the finger a distance at least as great as the distance between adjacent surfaces of adjacent ribs. The intermediate portion 58 of each finger merges relatively abruptly into the outer end portion and into the abutment 54.
The cylinder 50 is provided with diametrically aligned holes and in inserting the doublefinger therein the finger is stretched so-thatthe outer end portion and the abutment 54 are reduced'in transverse dimension and can readily be inserted therethrough. As the double finger is centered, it recovers its original shape and the abutments 54 secure the fingers in the cylinder.
Picking action of the finger "In connection with the finger illustrated in Figure 3,'the outer end 42 is of greater mass per unit length than the central portion 38 which is also considered a weak portion. As the drum rotates with considerable speed the centrifugal force developed throws the outer heavy end of the finger outwardly and since the intermediate portion 38 is weaker, the finger stretches in this portion. As the finger strikes the fowl, its cen trifugal force is lost, and the weak intermediate section 38 then recovers its original shape while the finger is in contact with the fowl. The outer end of the finger is thereby given a short quick jerk.
When the finger strikes the fowl, as just described, the ribs flex over against one another and'pinch the feathers therebetween. This is made possible by the fact that the ribs have a radial extent at least as great as the distance between the ribs. When the finger is given a snap or jerk, it pulls out the feathers which are pinched between the ribs.
The finger bounces off the fowl, and as the V drum continues to rotate,-- the finger is carried across the fowl, but the fingerdoes not regain sufficient momentum or centrifugal force to rub with any appreciable pressure on the fowl, the finger has lost its original momentum, and the length of the fowl is so short that the finger cannot fi'y out again within the range of the fowl. V The finger may drag across the fowl, but this action is not considered rubbing, at least with such pressure as would cause barking of the skin. 7 Thus the picking action consists essentially in striking," with objectionable rubbing eliminated. p
I wish "to point out an important feature at this point: the skin of a fowl is somewhat loose and moves with respect to the flesh to a certain extent. If a picking finger strikes the fowl,'and moves or rubs a distance no greater than the distance which skin moves on the fiesh, the finger V cavity.
does not actually move over the surface of the skin. The length of the short snap or jerk given the finger, as in the present invention as explained above, is within the range of movement of the skin with respect to the flesh.
I have found that by providing the cavity 48 in the outer end of the finger, the mass of the outer end can be determined by the size of the It will be evident, however, that the total mass of the outer end portion 42 and the tapered portion 40 is greater per unit length than of the intermediate portion 38. It is also true that the intermediate portion 38 is of less mass per unit length than the inner end portion of the finger which includes the tapered portion 36 and the enlarged portion 30. Thus, when centrifugal action is developed, the finger stretches in the intermediate section 38.
The finger illustrated in Figure 3 is intended to be used in picking the body of the fowl and is of sufficient length that when a number of them are applied to the fowl they reach substantially all parts of the fowl.
In the double finger illustrated in Figure 5, each single finger is considerably smaller than the finger of Figure 3. The double finger of Figure 5 is intended to be employed for removin the garter feathers from the fowl andbecause of the restricted areas of operation the length of the finger and the diameter of the cylinder supporting them are of lesser dimension. The double finger of Figure 5, therefore, furnishes a convenient means for securing or mounting fingers on a small diameter cylinder.
Each single finger of Figure 5 is essentially the same as the finger of Figure 3, but is varied in detail. The intermediate portion 58 of each finger is of less mass per unit length than the central portion 52 and it is also, of course, of less mass than the abutment 54. The intermediate '40 portion 58 is also of less mass per unit length than the outer portion 60. Thus, when the drum or cylinder 50 rotates, the centrifugal force causes the outer end of the finger to fiy out and the finger stretches in the weak portion 58. Stretching of the central portion 52 is prevented because of the fact that it is heavier than the portion 5 8. The action of the ribs 62 is the same as described in connection with the ribs 44. The fingers 56 of Figure 5 are not provided with cavities such as in the finger 25, but it is understood that such cavities may be employed for the purpose of providing the correct proportions of mass. between the outer end and the intermediate portion 53.
While I have herein shown and described certain embodiments of my invention, manifestly they are susceptible of modification without departing from the spirit and scope thereof. I do not, therefore, wish to be understood as limiting my invention to the precise forms herein disclosed, except as I may be so limited by the appended claims.
I claim as my invention:
1. An elongated and elastic poultry picking finger comprising a base portion adapted for securement to a rotatable supporting member, an intermediate shank portion, and a cylindrical outer end portion, said intermediate shank portion being of lesser outer transverse dimension and lesser cross sectional area than both said base portion and said outer end portion, Whereby said intermediate shank portion stretches longitudinally by centrifugal force upon rotation of said supporting member more easily than both of said other portions, and whereby said intermediate shank portion bends transversely more easily than both of said other portions, and a plurality of axially spaced circumferential ribs on said outer end portion extending radially therefrom, all of said ribs extending beyond the cylindrical periphery of the outer end portion .of the finger a distance at least as great as the distance between adjacent surfaces-of adjacent ribs. 1
2. A poultry picking finger as set forth in claim 1 wherein both the base portion and the outer end portion taper over a portion of their length into said intermediate shank portion.
3. A poultry picking finger as set forth in claim 1 wherein said outer end portion has an axial cavity formed in the outer end thereof.
